本科生毕业设计说明书6110连杆钻小头孔组合机床设计摘 要： 组合机床是以通用部件为基础，配以工件特定外形和加工工艺设计的专用部件和夹具，组成的半自动或自动专用机床。它一般采用多轴、多刀、多工序、多面或多工位同时加工的方式，生产效率比通用机床高几倍至几十倍。由于通用部件已经标准化和系列化，可根据需要灵活配置，能缩短设计和制造周期。因此，组合机床兼有低成本和高效率的优点，在大批量生产中得到广泛的应用，并可以组成自动生产线。本课题来源于江苏高精机电设备有限公司。根据6110连杆的加工工艺要求，设计一台加工连杆小头孔的钻孔组合机床。主要完成机床总体设计、工序图、尺寸联系图、加工示意图、生产率计算卡、PLC控制原理图等设计任务。本设计在充分数据计算的基础上对标准通用零件做了仔细选择。并依据被加工零件的结构特点、加工部位的尺寸精度、表面粗糙度要求，以及定位加紧方式、工艺方法和加工过程所采用的刀具、生产率、切削用量情况等，设计了结构合理的多轴箱。关键词：组合机床；钻孔；PLC；多轴箱6110 connecting rod small end hole drilling machine tool designAbstract: With the general components as the basic structure, the combined machine toll is a king of semi-automatic or automatic specific machine composed by the specific components and clamps for the specific workpiece shape and processing technology design. It generally applies stamulous processing from the aspects of multi-axle, multi-cutter, multi-procedure, multi-surface or multi-station so that the production efficiency is several times and even more higher than the general machine tool. Owing to the standardization and serialization of the general components, the configuration can be made flexibly to shorten the circle of design and manufacture.Therefore, with the advantages of low cost and high efficiency, the combined machine tool is applied to the production in a large quantity and to form the automatic production line.This subject comes from Jiangsu high-precision mechanical and electrical equipment Limited Company. According to the processing requirements of 6110 connecting rod, to design a drilling machine tool which can process the hole of the small end. I complete the overall design of the tools, process maps, contact map size, processing diagram, Productivity Computing cards, PLC control schematics and other design tasks. On the basis of the complete data calculation, the standard general parts is chosen. The multi-axle box with reasonable structure is designed based on the structural features of the processed parts, the dimension precision of the processing sites, the surface roughness, the locating and clamping ways, the technological approach as well as the cutter, production effi
